The board on Friday wrote that Clinton’s knowledge of domestic and foreign affairs is superior to her opponent Bernie Sanders’ and her policy platforms on healthcare and financial regulation “more realistic” than the Vermont senator’s, Politico reported.

The editorial noted Clinton’s “liabilities as a candidate” included “a penchant for secrecy and self-protection,” and criticised her decision to use a private email server as Secretary of State.

The board characterised Sanders’ objectives as admirable but naive, comparing and contrasting his campaign and political vision with President Barack Obama’s.

The board gave Sanders credit for pulling Clinton left on economic inequality and noted that they disagreed with the proposition that Sanders supporters should admit defeat and vote for Clinton in California.

“Voters should choose the candidate they consider best qualified,” the board wrote.

“This page has endorsed Clinton not because she is more likely to win the nomination but because she is vastly better prepared than Sanders for the presidency.”
